Research on Application Technology of Biogas Slurry in Protected Cultivation of Cucumber

We carried out the experiment to study the effects of spraying different concentrations of biogas slurry on cucumber growth and yield in protected field. The results showed that, spraying biogas slurry could improve fruit quality of cucumber, and the fruit was straight and bright green. The plant had stronger growth potential, and plant disease and insect incidence was reduced significantly. While sprayed with 40% biogas slurry, the cucumber yield was highest of8 463.65 kg/667 m2 and the soluble solids content reached to 3.0%, which were increased by 10.19% and 36.36%compared with the control respectively. In addition, the vitamin C content was 8.5 mg/100 g, which was 8.97% higher than that of the control.
